Surprising consistency with pre-RoSaT SSJ Gotenks' lowball ending up less than 50% stronger than SSJ3 Goku, in line with Goku's claim that Gotenks will be stronger than himself. Could pump up EoZ Goku further like making post-Kid Buu saga SSJ3 Goku = Buuhan like in V-Jump. This way Gohan's left behind far enough that Uub would be a more appealing option for the fight Goku wants.
Now the real question is how to make a fusion formula that can work with this.
